Question

List 2 possible sources of error in the determining the molar mass of an unknown metal.

Answer 1

- Failure to properly maintain the temperature of the experiment, thus changing the pressure.

- Failure to react all of the unknown metal, thus failing to produce the expected amount of other products, and disrupting all subsequent calculations.

- Human error is always in effect, given that the laboratory does not function under ideal conditions. As such, there is always the possibility of inaccuracies in measurement, the perception of measurement, inaccuracies of equipment, and other such errors.
